EXAMPLE (Intake):
Measured valve clearance = 0.45 mm (0.0177 in.)
0.45 mm (0.0177 in.) - 0.20 mm (0.0079 in.) = 0.25 mm (0.0098 in.)
(Measured - Specification = Excess clearance)
Used shim measurement = 2.80 mm (0.1102 in.)
0.25 mm (0.0098 in.) + 2.80 mm (0.1102 in.) = 3.05 mm (0.1201 in.)
(Excess clearance + Used shim = Ideal new shim)
Closest new shim = 3.05 mm (0.1201 in.)

(d) Using a small screwdriver and magnetic finger, remove
the adjusting shim.
(e) Using a micrometer, measure the thickness of the re-

AThickness of new shim
BThickness of used shim
CMeasured valve clearance
Specified value (Cold):
Intake A = B + (C - 0.20 mm (0.0079 in.))
Exhaust A = B + (C - 0.30 mm (0.0118 in.))
(g) Select a new shim with a thickness which is as close to the
calculated values as possible.
HINT:

Shims are available in 17 sizes in increments of 0.05 mm
(0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 mm
(0.1299 in.).
